Plugin Config Schema Audit and Standardization - Summary

Overview

Completed comprehensive audit and standardization of all 12 plugin configuration schemas in the LEDMatrix project.

Results

Validation Status

• ✅ All 12 schemas pass JSON Schema Draft-07 validation
• ✅ All schemas successfully load via SchemaManager
• ✅ All schemas generate default configurations correctly

Standardization Achievements

1. Common Fields Standardized

   • ✅ All plugins now have enabled as the first property
   • ✅ All plugins have standardized display_duration field (where applicable)
   • ✅ Added live_priority to plugins that support live content
   • ✅ Added high_performance_transitions to all plugins
   • ✅ Added transition object to all plugins
   • ✅ Standardized update_interval naming (replaced update_interval_seconds where appropriate)

2. Metadata Improvements

   • ✅ Added title field to all schemas (12/12)
   • ✅ Added description field to all schemas (12/12)
   • ✅ Improved descriptions to be clearer and more user-friendly

3. Property Ordering

   • ✅ All schemas follow consistent ordering: common fields first, then plugin-specific
   • ✅ Order: enabled → display_duration → live_priority → high_performance_transitions → update_interval → transition → plugin-specific

4. Formatting

   • ✅ Consistent 2-space indentation throughout
   • ✅ Consistent spacing and structure
   • ✅ All schemas use additionalProperties: false for strict validation

Plugins Updated

3. football-scoreboard - Reordered properties (enabled first), added common fields, standardized naming
4. hockey-scoreboard - Added title, description, common fields, standardized naming
5. ledmatrix-flights - Added common fields
6. ledmatrix-leaderboard - Added common fields, moved update_interval to top level
7. ledmatrix-stocks - Added common fields, fixed update_interval type
8. ledmatrix-weather - Added missing enabled field, added title/description, reordered properties, added common fields
9. odds-ticker - Added common fields
10. static-image - Added title and description
11. text-display - Added title, description, common fields, improved descriptions

Key Changes by Plugin

clock-simple

• Added title and description
• Added live_priority, high_performance_transitions, transition
• Improved field descriptions
• Reordered properties

text-display

• Added title and description
• Added live_priority, high_performance_transitions, update_interval, transition
• Improved field descriptions
• Reordered properties

ledmatrix-weather

• Critical fix: Added missing enabled field (was completely missing)
• Added title and description
• Reordered properties (enabled first)
• Added live_priority, high_performance_transitions, transition
• Added enabled to required fields

football-scoreboard

• Reordered properties (enabled first)
• Renamed update_interval_seconds to update_interval at top level
• Added live_priority, high_performance_transitions, transition
• Added enabled to required fields
• Improved title and description

hockey-scoreboard

• Added title and description
• Renamed top-level update_interval_seconds to update_interval
• Added live_priority, high_performance_transitions, transition
• Note: Nested league configs still use update_interval_seconds (intentional for clarity in nested contexts)

baseball-scoreboard

• Renamed update_interval_seconds to update_interval at top level
• Added high_performance_transitions, transition
• Note: Nested league configs still use update_interval_seconds (intentional)

ledmatrix-leaderboard

• Added display_duration, live_priority, high_performance_transitions, update_interval, transition at top level
• Removed duplicate update_interval from global object (moved to top level)

ledmatrix-stocks

• Changed update_interval type from number to integer
• Added live_priority, high_performance_transitions, transition

odds-ticker

• Added live_priority, high_performance_transitions, transition

ledmatrix-flights

• Added live_priority, high_performance_transitions, transition

static-image

• Added title and description

Notes on "Duplicates"

The analysis script detected many "duplicate" fields, but these are false positives. The script flags nested objects with the same field names (e.g., enabled in multiple nested objects), which is valid and expected in JSON Schema. These are not actual duplicates - they're properly scoped within their respective object contexts.

For example:

• enabled at root level vs enabled in nfl.enabled - these are different properties in different contexts
• dynamic_duration at root vs nfl.dynamic_duration - these are separate, valid nested configurations

Validation Alignment

The validate_config() methods in plugin managers focus on business logic validation (e.g., timezone validation, enum checks), while the JSON Schema handles:

• Type validation
• Constraint validation (min/max, pattern matching)
• Required field validation
• Default value application

This separation is correct and follows best practices.

Testing

All schemas were verified to:

1. ✅ Pass JSON Schema Draft-07 validation
2. ✅ Load successfully via SchemaManager
3. ✅ Generate default configurations correctly
4. ✅ Have consistent formatting and structure

Next Steps (Optional)

1. Consider updating plugin manager code that uses update_interval_seconds to use update_interval for consistency (if not in nested contexts)
2. Review validate_config() methods to ensure they align with schema constraints (most already do)
3. Consider adding more detailed enum descriptions where helpful
